Increment Operator Example Java Program

Definition

Operators are constructs which behave generally like functions, but which differ syntactically or semantically from usual functions. Common simple examples include arithmetic (addition with +, comparison with >) and logical operations (such as AND or &&). More involved examples include assignment (usually = or :=), field access in a record or object (usually .), and the scope resolution operator (often ::). Addition and assignment operator means "find the number stored in the variable x, add 1 to it, and store the result of the addition in the variable x." The increment operator increases the value of its operand by 1. The operand must have an arithmetic or pointer data type, and must refer to a modifiable data object.

x=y++;

class IncrementOperatorDemo {
	public static void main(String[] args) {
		for (int i = 1; i < 10; i += 2) {
			for (int j = 0; j < 9 - i / 2; j++){
				System.out.print(" ");
			}
			for (int j = 0; j < i; j++){
				System.out.print("*");
			}
			System.out.print("\n");
		}
		for (int i = 7; i > 0; i -= 2) {
			for (int j = 0; j < 9 - i / 2; j++){
				System.out.print(" ");
			}
			for (int j = 0; j < i; j++)}
			System.out.print("*");
			}
			System.out.print("\n");
		}
	}
}

Output is:
         *
        ***
       *****
      *******
     *********
      *******
       *****
        ***
         *
